Update: took it back apart, plates were in correct order. BUT, pilot bearing had some damage on it likely from the install which likely was causing the output shaft to lock onto the e-shaft. Removed the damaged pilot bearing using the bread trick and installed a extra one I had. I have the engine and transmission only a 0.5-.75 inches apart and cant seem to get the bell-housing to seat on the motor. Trying to thread the output shaft through the pressure plate, two discs, and the pilot bearing seems much more difficult than a standard single disc setup. This car has been giving me such headaches lately as nothing seems to want to go together.... I seriously need to get a lift.

Update: Car is back together and is up and running. Moved the car around in the garage with the new clutch. Shockingly smooth engagement for two 7.25" sintered discs. No chatter yet. The pedal pressure is about double, but I need to adjust the clutch rod because I am overthrowing the master/slave since the engagement point is 3/4 of the way off the floor. Pedal pressure may go down once I get it adjusted properly. After running for 15 minutes I have one drop of oil I have to track down since I resealed the front cover and oil pan with Toyota FIP Black. Hopefully a fitting only needs to be tightened. I also am removing my oil temp gauge and putting in a EGT gauge. I ended up putting the probe about 2 inches from the front PPort. Due to my manifold design, it was easier to install on the front. When I bought the junk engine, the front rotor was blown, and when I blew a piece of apex seal off it was also in the front rotor so why not. I also keep blasting vacuum caps off of the UIM, which is causing small vacuum leaks. I am now just using a piece of hose running from one port to another to seal it up. Car is idling at 1,400-1,500 RPMs and vacuum is 12-13". Still have to do some finishing details and should be able to give a full review of the Spec Mini Twin Disc D-Trim for the rx8....

Put about 50 miles on the car today. Engagement is smooth, no chattering, and slips into gear real nice. There is about a half-inch or inch of travel on the clutch from full off to full on. You have to be careful to release the clutch just right. Don't release high enough and the car just sits there. Release too high and the car jumps forward and will likely stall. Way smoother than the 6 puck clutch, but harder to hit that sweet spot. After some adjustment, pedal pressure still seems about 50% more than stock, which is fine since the rx8 clutch from factory is super light. Only stalled it once getting used to the engagement point. By the way the car jumped after letting out a tad quick gives you the feeling that this will hold some serious power. With the clutch in I get the normal multi-disc clutch noise, but it is not loud at all (sounds like a vibrating symbol instrument, not like rocks bouncing around in the bell-housing like the Supras have). On about 10-15% of the times I shift the car I get a bit of squeal, but this seems to happen most on downshifts and shifting into high gear without many RPMs. All in all I believe I will be able to slip the car into gear at the track without too much trouble and it should be able to hold all that torque that a 13b will produce. I also can't get the EGT to get a signal from the probe, but I had to extend the harness and it was shielded so I will have to call Prosport to see what they think.

So for a run down of the changes to the car.

New Master Cylinder (replaced original)
New Slave Cylinder (replaced original)
New clutch fluid (replaced original)
New Serpentine and AC belts (replaced original)
Resealed the front cover and oil pan with Toyota FIP Black
Welded EGT bung in manifold (2" from PPort) with EGT gauge (to replace oil temp)
Found a small exhaust leak on the down-pipe and re-welded
Rear Counterweight for FD
SPEC Steel Flywheel
SPEC Twin Disc (D-Trim) - 800 lb/tq rated
Oil change - 10w-40
Flushed coolant

Fixed the EGT gauge. The harness was faulty the way it came. Found a bad spot in the wire with a ohm meter and re-soldered.

The EGT probe is mounted literally 2 inches from the front PPort. Was seeing about 800F (12.5-13:1 AF, 1,500 RPMs, 20 Leading) on startup idle. 1,300-1,600F cruising around at 14.5-15:1 A/F, 32 Leading (need to richen it up a point to bring those down). After the car was warmed up, I was seeing a 1,200F idle (13:1 AF).... Its wet outside so no power pulls.

Those values were on E50 fuel so they'd likely be higher if I were on 93. Once this front passes and it dries out I will get to see what EGTs I get with E50 and water/meth injection.

I read 750-850celcius while cruisin at 3500rpm, 14afr, idle is like 500-550c

I have 2 sensors, both are pre turbo, one in each runner

the highest egt i read is when i cruise, as soon as i do a pull they drop alot and then rise back up

I was wondering why my manifold/turbo/db was glowing before, now i know lol

I added more timing in the idle and cruising parts of the map and my manifold doesn't seem to glow as bright. I was shocked how high the EGTs were at cruising.

What I find amazing is that my manifold is schedule 40 mild steel, and when I had the car apart last weekend that manifold looks as good as the day I welded it up. It doesn't seem to have warped or anything, and thats with maybe a hundred hours of glowing red/pink.....

I tried to do a power pull yesterday to log EGT, but at 20+ psi and 7,000 RPMs in second gear i blew a charge pipe off and it scared the hell out of me. Seemed like the EGTs were starting to dip a bit, but I was only at WOT for like 2-3 seconds. Luckily with MAP tuning I was able to drive it all the way home without the turbo. I'm going to try and spray the ends of the charge pipes with hair spray which should help.

On December 29th in Bradenton, FL they are going to have a test and tune roll-race event and drag racing event from like 1 pm to midnight. Gotta try to have everything fixed by then so I can try to blow it up.

Dumb question but is the end of your piping rolled? When I was just messing with mine I noticed one wasn’t and I made a “roller” out of some vice grips.

Yep they are that is a good idea though. I used a thin coat of hylomar which gets real tacky when it dries. The pipes are now holding....

New video to check out my new EGT gauge.
Was a quick blast from 45-95 mph in 3rd gear just shy of 10mph/s. Will go up through 4th on a better road.
Went from about 1,400F to 1,650F and that with it going lean up top.
Turbo is real responsive in the cold, 10 psi by 3,600, 20 psi by 4,500
MAP sensor seems to be acting up again in the vacuum readings
I have a drive-train vibration like I didn't align the PPF correctly.
Will sort it all out in time.
